1.2 Warnings and Cautions
Caution: US federal law restricts this device to sale by or on the order of a licensed
healthcare practitioner. This product should be used only under the supervision of
a physician.
1.2.1 Warnings
The following warnings indicate the possibility of injury to the patient or the operator.
• Be aware of signal interference, which can occur from external sources. Electronic
signals are required for the Alice 5 to function. Even though the system contains methods
and techniques that can provide protection from external sources of interference, you
should operate the system as follows:
– Do not plug sensor lead wires into electrical outlets. Lead wire contact with electrical
outlets presents a serious shock hazard.
–Place the system components on a sturdy and level surface. Do not place the base
station on carpeting.
– Do not use the Alice 5 system within three feet of oxygen tanks or oxygen tents.
– Do not operate the Alice 5 system in any explosive situation where flammable or
explosive sources are operational and in use.
– If you suspect that the system is not working properly, do not attempt to service it.
Contact your equipment provider or Respironics for assistance.
–Always unplug the components from all electrical power sources (AC) when
cleaning the system or any of its accessories. To remove AC power, unplug the
power supply cord from the mains outlet.
– Do not connect telephone equipment to the auxiliary inputs.
• If a patient has a cardiac pacemaker, consult with the patient’s physician prior to performing the study.
• The Alice 5 device and its accessories are not protected against the effect of cardiac
defibrillation. Remove all patient leads (applied parts) before performing cardiac defibrillation.
• Do not use the Alice 5 system in a Magnetic Resonance Imaging (MRI) environment or
in close proximity to a high emissions source.
• Do not touch the base station and the patient simultaneously, as this may create an
electrical shock hazard.
• Periodically inspect the electrical cords, cables, and the power supply device for damage
or signs of wear. Discard and replace any damaged parts before using.
1–4
Alice® 5 Setup and User’s Guide
• Make sure that any wires attached to the patient are routed to reduce the likelihood of
strangulation.
•Pins of connectors identified with the ESD warning symbol should not be touched.
Connections should not be made to these connectors unless ESD precautionary procedures are used. Precautionary procedures include methods to prevent buildup of electrostatic discharge (e.g., air conditioning, humidification, conductive floor coverings, and
non-synthetic clothing), discharging one’s body to the frame of the equipment or system
or to earth or a large metal object, and bonding oneself by means of a wrist strap to the
equipment or system, or to earth.
• The conductive parts of electrodes and associated connectors, including the neutral
electrode, should not contact other conductive parts, including earth.
• Do not use during high frequency surgical procedures or electrosurgery.
1.2.2 Cautions
The following cautions indicate the possibility of damage to the device.
• For all equipment used with the Alice 5 system, follow all of the manufacturer’s recommendations and instructions. Be sure to read, understand, and follow the instructions in
this manual and others that come with the system and its components. If you don’t have a
manual, ask the equipment distributor or manufacturer for one.
• Operation of the Alice system may be adversely affected by:
–electromagnetic fields exceeding the level of 10 V/m in the test conditions of EN
60601-1-2
–the operation of high frequency (diathermy) equipment
– defibrillators, or short wave therapy equipment
–radiation (e.g., x-ray, CT)
– magnetic fields (e.g., MRI)
• Synthetic fabric from draperies or rugs can also cause interference due to static electricity. Touching an inanimate object (e.g., wall, crib) before handling the patient or the
system often prevents static build-up problems.
•Strong transmitter signals from TV, radio, airport, police, fire, and ambulance stations
could be received and interpreted as heart and/or breath signals. If you are located less
than one mile from any of these sources, ask Respironics Customer Service to assist you
in determining whether your system will operate properly.
• Do not soak or immerse the base station or headbox in any liquid.
• Never use an extension cord with the Alice 5 system. Always operate the device using a
properly grounded AC power outlet. If you are unsure whether a power outlet is properly
grounded, contact an electrician for assistance.
Introduction
1–5
• Do not place liquids on or near the Alice 5 system. If liquids are spilled on the equipment,
discontinue use until it can be determined that the device can be safely operated. Contact
Respironics for assistance.
• Do not operate the Alice 5 system during electrical storms. Information could be lost or
damaged.
• Do not drop components of the Alice 5 system. If any of the devices are dropped,
discontinue use until it can be determined that the device is fully operational. Contact
Respironics for assistance.
• Report problems with any of the components of the Alice 5 system. If the system is not
working properly, contact Respironics immediately for service.
•Use only accessories that have been approved by Respironics.
1.3 Intended Use
The Alice 5 system is a single-patient use, polysomnography system that is intended to record,
display, and print physiological information for clinicians or physicians. These parameters are
presented graphically on a computer screen for diagnostic review, similar in application to the
use of a traditional paper-based polygraph recorder. The device will be used in hospitals, institutions, sleep center or clinics, or other test environments where adults or infant patients require the
documentation of various sleep or other physiological disorders.
This device does not provide alarms and is not intended for use as an automated apnea monitor. It
is not for continuous monitoring.
The Alice 5 equipment collects the data from sensors placed on a patient and delivers the data to
a computer running the Sleepware application. The Alice Sleepware application is a Windowsbased software program designed to monitor, display, process, and download polysomnographic
data recorded with the Alice 5 equipment.
Note: For information about using Microsoft Windows, refer to your Microsoft documenta-
tion. For more information about Alice Sleepware, refer to the Alice Sleepware User’s
Guide.

Alice® 5 Setup and User’s Guide
1.4 Hardware Component Overview
The Alice 5 equipment consists of the base station, headbox, polysomnographic sensors, and
auxiliary input devices.
The base station and headbox record, amplify, filter, and digitize various physiologic inputs. It
may collect up to 55 channels of data. The base station stores the data locally on an internal hard
disk until it is sent over a wired or wireless ethernet connection to a computer running the Alice
Sleepware application. Sleepware can display live or pre-recorded data in a resolution consistent
with the computer hardware specifications. Sound and video of the patient are available, and an
intercom feature allows you to communicate with the patient remotely.
The base station can also interface directly with several auxiliary input devices (e.g., EtCO
monitors, etc.).
The two main components of your Alice 5 system are the base station and headbox. You can add
additional hardware components, such as video cameras, if needed. See Chapter 2 for information on how to set up video cameras. For information on additional Alice 5 accessories, refer to
the Respironics Diagnostic Accessory Guide.

1.4.1 Data Flow through the Alice 5 Components
The flow of the data through the Alice 5 system is as follows: From the patient, the sensors pick
up physiologic events. Sensor cables carry the signal to the Alice 5 headbox or to an auxiliary
device.
If the data then gets carried to the Alice 5 base station via the headbox, the signal is amplified
and treated before being transformed from analog to digital format. If the signal is sent to the
base station via an auxiliary input, it is not amplified by the base station because it was already
amplified and conditioned in the auxiliary unit.
The signals are digitized and stored in the base station. If configured, they are then sent from the
base station to the computer running the Alice Sleepware diagnostic application.
Figure 1–2 illustrates the flow of data during an Alice 5 acquisition.

•Off – Indicates that data is not being captured or recorded (i.e., a study is not in progress).
3. Audio/Video – The bottom LED is the camera/microphone recording indicator and has the
following states:
•Green – Indicates that video and/or sound is active or being recorded.
•Off – Indicates that video and sound are not active or being recorded.
In addition to the LEDs above, the control panel also includes the following button:
• Record Start/Stop – You can use this button to start or stop a data acquisition directly
from the base station. If you start an acquisition at the base station, the name and ID of
the previous patient is used, and the default configuration is recorded. For more information on data acquisitions, see Chapter 4.
Note: Data acquisitions can also be started from a computer running Alice Sleepware. When
starting acquisitions from a computer, you can enter specific patient information.
The Infrared Transceiver on the front of the base station (shown in Figure 1–3) allows the base
station to communicate with a laptop computer. If you are using a laptop that does not have a
wireless card, the laptop can still communicate with the base station if it has infrared (IRDA)
capability.

1.4.3 Headbox
The Alice 5 headbox combines the neurological inputs and cardio-respiratory inputs into a single
device. These signals are then sent to the Alice 5 base station. You can place the headbox in
several different locations:
• On a table or stand beside the patient’s head.
•In the headbox mounting bracket attached to the wall behind the patient’s head.
•Attached to a carrying strap that the patient can wear around the neck. This option is
useful if the patient needs to get up during the study so the connectors do not need
removed.
•In the headbox pouch attached to a shoulder strap worn over the patient’s shoulder.
Figure 1–5 illustrates the options for headbox placement.

End tidal carbon dioxide, as detected by an end tidal CO2 monitoring device.
Generic Channels Channels whose data the Alice 5 does not have an auto-scoring
algorithm for. Generic channels need definition regarding their
presentation (display). Generic channels usually have as their
source an auxiliary device connected to an auxiliary input on the
Alice headbox. Generic channels may be displayed as numbers or
graphs. There are three display types for generic channels:
Graphic, Grapho-Numeric, and Numeric.
Graphic Display Type One of three display types for generic channels. A graphic display
type is assigned when a channel’s data is most useful to the
clinician when displayed as a graph (waveform) rather than a
number, and the data points of the curve are not clinically useful.
In other words, the curve, not its data points, are important.
Grapho-Numeric Display Type
One of three display types for generic channels. A grapho-numeric
display type is assigned when a channel’s data is most useful to the
clinician when displayed as a graph (waveform) and the data points
are also meaningful.
Headbox A bedside remote amplifier that is part of the Alice system and is
used to collect physiologic data from sensors placed on the
patient’s body.

MAC Address Media Access Control address. This is a unique hardware address
that identifies a device on a network. It is assigned by the manufacturer and cannot be changed. This address can usually be found on
the device packaging.
Montage A montage (as distinguished from an acquisition configuration) is a
way to display re-referenced EEG and EOG data during or after an
acquisition. Each acquired EEG channel measures the difference in
electrical potential between a given (active) electrode and a
reference. The montage tool recombines EEG/EOG data in order to
display the difference in potential between any two electrodes.
Numeric Display Type One of the three display types for generic channels. A numeric
display type is assigned when the data is most useful to the

Alice 5 Equipment Setup
This chapter describes how to connect the hardware components included with the Alice 5
system. It contains graphics illustrating the connections as well as detailed step-by-step instructions.
There are several possible ways to set up your Alice 5 system:
• Wired point-to-point setup, where wired devices communicate directly with each other
(e.g., base station to computer).
• Wired network setup, where a switch is used to connect multiple devices to a Local
Area Network (LAN).
• Wireless ad-hoc setup, a wireless networking framework in which devices communicate
directly with each other, without the use of an access point.
• Wireless Access Point Infrastructure network setup, where a device acts as a commu-
nication hub for users of a wireless device to connect to a wired LAN.
This chapter provides general instructions on how to set up each of these systems. The examples
provided are suggested ways of positioning the equipment. You may alter the component setup as
needed.

2.1 Before You Begin
Before you set up your Alice 5 system, keep the following information in mind:
• Map out your facility’s layout in advance so you know what type of equipment, cables,
and accessories you will need.
• Determine whether you will be setting up a wired or wireless network for Alice 5. If you
will have a wired network with multiple devices connected, you will need a switch.
• Respironics recommends that you set up the Alice system on its own network, independent of your facility’s network(s). System performance may be better on an independent
network.
•Your cabling requirements will change depending on whether you use a point-to-point
setup or a network setup. You will need a CAT-5 Crossover cable for a point-to-point
setup, while a network setup requires a standard CAT-5 Patch cable.
• The Alice 5 system does not support the Dynamic Host Configuration Protocol (DHCP),
a protocol for assigning dynamic IP addresses to devices on a network. You must assign
static IP addresses to your Alice 5 devices and to the computers you are running the Alice
Sleepware software on, as well as to any network video cameras or servers you use. See
Chapter 3, Software Installation and Setup, for additional information.
2.2 Setting Up Your Network
This section describes how to install your system using wired or wireless networks.
2.2.1 Network Setup Examples
This section provides example illustrations of various setups that are commonly used when
configuring Alice 5 networks. There are many possible configurations, but these will help you
understand some of the basic connections and how the IP addresses are set up. The different
wired and wireless setups are described in greater detail in Sections 2.2.2 – 2.2.4.
Note: It’s recommended that you first map your network setup before proceeding with the
equipment installation instructions later in this chapter and the software installation
described in Chapter 3. You will need to determine what your network configuration is
and what equipment you’ll be using (if you’ll need a switch, a video server, etc.) before
you start setting everything up.
